The number of packets exchanged per connection event depend on the capabilities of both devices and that there is data to send. The BLE specification does not regulate this directly. The nRF will typically a new packet as long as the connection event (time) has not expired <em>and</em>&nbsp;there is already buffered data ready to be sent (which typically depend on the number of TX buffers reserved for the SoftDevice).</p> <p>2. I suspect 100 packets per connection event is difficult. In any case you should remember that the throughput also depends on other factors such as connection interval, connection event length, the packet length. Also, the support for the various parameters differ greatly for different phones.</p><div style="clear:both;"></div>
